using IM commands from Java

[gaurav_kl]

I am trying to run a simple IM command from a Java class and as I have to run only a few commands I thought
instead of using Im4Java ,I could directly use ProcessBuilder.start().
I am using the following code-

Code: Select all

ProcessBuilder pb = new ProcessBuilder("convert","pic2.png","pic52.png");
			 pb.directory(new File("/user/gaurav_kl"));
			pb.start();

but I am getting the error
IOException - Cannot run program "convert" (in directory "/user/gaurav_kl"): error=2, No such file or directory
What could be the reason.
when I run the same command from terminal it works fine from any Dir as IM has been added to classpath

try putting in the full path to convert

if you do not know it, type at a console

type -a convert

or

which convert

thanks.it worked.
i had thought it was already added in the PATH .

Many scripting systems do not check the PATH. Typical with PHP, Applescript, etc
